Apparatus for monitoring the structural health of a column or a stock of columns or a column or columns within that stock is disclosed in the application. The apparatus comprises a microcontroller located on the or each column which includes an integrated MEMS device programmed to measure and record accelerations, angular velocities and magnetic field strengths in X, Y and Z axes. The apparatus includes means for connecting said microcontroller to a source of power, and means operable to transmit said measured data to a central data hub and from there to a remote server for analysis using bespoke software.

A load monitoring device including a substrate having a first surface. The monitoring device further including a conductive portion coupled to the first surface of the substrate comprising a first portion, a second portion, and a failure region separating the first portion and the second portion. The conductive portion is pre-tensioned to induce a failure in the failure region when a predefined amount of tensional force is applied to the substrate.

Modifying a motion plan for an autonomously-operated inspection platform (AIP) includes obtaining sensor data for an industrial asset area of interest, analyzing the obtained sensor data during execution of an initial motion plan to determine if modification of the initial motion plan is required. If modification is required then performing a pose estimation on a first group of potential targets and a second group of potential targets, optimizing the results of the pose estimation to determine a modification to the initial motion plan, performing reactive planning to the initial motion plan to include the modification, the reactive planning providing a modified motion plan that includes a series of waypoints defining a modified path, and autonomously controlling motion of the AIP along the modified path. The analysis, pose estimation, optimization, and reactive planning occurring during movement of the AIP along a motion plan. A system and computer-readable medium are disclosed.

The present invention relates to quality control of pulmonary function test (PFT) devices. In particular, but not by way of limitation, the present invention relates to systems and methods for characterizing or verifying the measurement accuracy of pulmonary function testing devices used for measuring dynamic lung volumes (tidal volume (TV), inspiratory reserve volume (IRV), expiratory reserve volume (ERV), divisions thereof, and any other suitable dynamic lung volume) using spirometry, static and/or absolute lung volumes (total lung capacity (TLC), residual volume (RV), divisions thereof, and any other suitable absolute lung volume) using washout, dilution, and/or plethysmographic methods, and/or gas exchange, such as single-breath determination of carbon monoxide uptake in the lung (D.sub.LCO).

A tester for evaluating pullout load capacity and bond quality of anchor bolts embedded in concrete includes a Schmidt hammer for measuring a rebound number and an ultrasonic pulse velocity tester for measuring the transit time of a pulse transmitted through concrete surrounding an anchor bolt. The rebound number and the transit time are combined and matched against a database record which identifies the pullout load capacity and the bond quality. The transit time is matched to thresholds of transit times associated with porosity, internal cracking, air voids, and water pockets located around the embedded anchor bolt. The Schmidt hammer is further modified by the incorporation of a digital level for measuring the vertical and horizontal angles of inclination of the plunger with the concrete surface, a guide tube for supporting the plunger, and by using a convex plunger tip for improved registration with anchor bolt head.

Systems and methods to measure fluid delivery times in a piping system and more particularly a dry pipe fire protection system. A device is provided that includes at least a solenoid valve for coupling to a network of pipes of a dry pipe sprinkler system and a liquid detector for coupling to the network of pipes to detect a flow of water in the network. A timer is coupled to the solenoid valve. Upon operation of the solenoid valve, the timer simultaneously initiates a start time of a fluid detection test. The timer is preferably coupled to the liquid detector such that upon the detector detecting water, the timer defines a stop time of the fluid detection test.
